SYLVESTRE KRNKA, OF PARIS, FRANCE.

BOTTLE-SEALING DEVICE.

Specification of Letters Patent.

Patented June 11, 1912.

Application filed June 28, 1909. Serial No. 504,909.

To all whom it may concern:

Be it known that I, SYLVESTRE KRNKA, a subject of the Emperor of Austria-Ih1ngary, residing at Paris, in France. have invented a certain new and useful Bottle- Sealing Device, of which the following is a specification.

Numerous arrangements of stoppers with corrugated collars have been designed, but none of them hasproved completely satisfactory. The best system seems to be that described in the United States Patent No. 468,226 granted to \Villiam Painter, February' 2, 1892, and consisting of a capsule, the collar of which forms a succession of hollows and ribs, and of which the only disadvantages are that it is difiioult to open, that it cannot be used for closing receptacles or other articles of small resistance, and that it can be tampered with. In fact, the said stopper can be replaced after having been removed, so that no trace of fraudulent manipulation thus effected is left.

The invention remedies the above disadvantages.

It relates to improvements made in the same arrangement, which will be clearly understood with the assistance of the following description and the accompanying rawlng.

" Figure 1 of the drawing shows, partly in elevation and partly in section, a construction of stopper in which some of the present improvements are embodied. Figs. 2 and 3 show on an enlarged scale, respectively in section and in elevation, a portion of the collar of the construct-ion shown in Fig. 1. Figs. 4-5 and 67 show in the same way two modified constructions of the said collar. Fig. 8 shows in elevation, ready to be placed on a neck with double ring, a complete stopper with a collar of the kind shown in Figs. 6 and 7. Fig. 9 shows in the same Way, but in position, the construction shown in Fig. 8. Fig. 10 shows in elevation a modified construction of the tongues with which the stopper forming the subject of this invention is provided.

'hese improvements consist chiefly in appiyin to the capsules of the above mentione type the well known device constituted by tongues and hitherto utilized only for stoppers without corrugated collars, in which, for the purpose of rendering them practical, it was necessary to use either a series of slots or some other weakening means, combined with the tongues, or else to use a very large number, or very large tongues. V

The present improvements relate, moreover, to special constructions of the above application which enable the various elements constituting the collar, to execute at the moment when the closing is being effected, the relative movements necessary for producing the closing and also enable the capsules themselves to be stamped out in one single operation of the press. According to these last methods of construction, recourse is had, as the means of strengthening (which as well known is always necessary) the tongues themselves, on the one hand, to the ribs b of the collar, and on the other hand, either, as shown in Fig. 1, to an extension of the recess of the hollow or hollows or reentering portions a which each tongue 0 touches, or as shown in Figs.

-810, to a combination of projecting longitudinal and transverse ribs, this enabling in addition to what has alread been stated, the uncorking or opening to bg effected with greatfacility. When, in fact, one of the tongues c (or the tongue, if there be only one) is moved upward as usual, the corresponding portion of the collar is bent about a line passing practically through the top of the ribs adjoining the tongue manipulated, and the result is that, on the one hand, the portions of the collar situated on both sides of the tongue which is manipulated are raised, and on the other hand, the capsule is torn. As thetearing takes place without fail when the tongue is operated for pushing it upward, which is a necessary condition for opening, the result is that the system is practically proof against tampering, as it cannot be fraudulently opened ex- Cept by acting by means of a suitable tool on the portions of the collar situated between the tongues, and at the same time taking'care not to touch thetongues. The

said tearing affecting, moreover, only the height of the collar of the capsule, that is say, the desired height for facilitating the opening, the said capsule remains intact regards its upper portion, so that it can still utilized as a cover.

.In order to make the impossibility of tampering more certain, it is possible, (in view of the fact that the use of tongues renders it unnecessary to have recourse to the shape hitherto used for the reentering portions of the collar, to which portions it was usual to give, in section and elevation, a shape similar to that shown in Figs. 2 and 3, so as to leave between the base of the capsule and the neck of the bottle or other receptacle, a certain annular space for introducing the opening tool) to give the said reentering portions, such a shape that they shouldhave in section and in elevation a form such as possihl shown in Figs. 4 and 5. lt is then merely necessary to have one weak point in the system; the projection 01 forming the bottom portion of the ribs 7 which however might possibly be attacked by means of a tool. In order to remove this last possibility of fraudulent tampering, it is suflicient to do away with the bottom portion of the reentering parts, owing to which it becomes e to give to the ribs or projecting parts 6 a pointed shape such, for instance, as that shown in Figs. 6 and 7, owing to which,-moreover, the forcing back of the said reenter-ing portions, required for closing the bottle, becomes much easier than was the case hitherto. The said parts which can be made so that they extend farther in the direction of the height, and also made to project farther inward at the moment of stamping out, can be thus made to fit the shape of the ring of the bottle or vessel completely, and the whole capsule can be made of much thinner metal (or other materia-l) than usual, so as to render'it suitable for closing articles of slight resistance and made in a cheaper manner.

In the last case considered, the sectional form of the collar is similar to that previously mentioned and shown in Fig. 2,.

with the difference that there are no horizontal portions such as d Fig. 4, or prac There is still left therefore between the bottom portion of the ribs and the ringof the article closed, a space suitable for the introduction of a tool; but the system nevertheless cannot be tampered with. In fact, owing to the fragility .of these ribs when they are constructed as described, as soon as an attempt is made to remove them from the 'DCClI, they break or become permanently deformed. or tear. It is, mpreover, easy to prevent entirely any possibility of attacking ribs designed in the above mentioned manner, by providing a groove in the closing ring on the neck of the article to be closed, or, still better, by making the same ring double as shown in Figs. 8 and 9. This} i is generally used for? arrangement which closing systen'is different from the one uni dcr consideration. was hitherto inapplicable to thelatter. Itwould have, in fact, rendered the opening impossible. According to this invention. on the contrary, the application in question becomes vcr 1 simple, without any difliculty in opening. As however in the case under consideration the second ring would interfere with the correct placing of the tongues, if they were made con cave as shown in Fig. 1, the said tongues are preferably given a form such as shown in Figs. 8 and 9, and obtained by bending the tongues inward twice, the first time about their symmetrical axis, which produces 0n the said tongues a more or less pronounced longitudinal rib e, and the second time about the line or lines f connecting the points of the ribs adjoining the tongues, the result of which is that this line or lines are rendered more or less projecting; The first bendin operation enables the tongues 0 to bend again, as is necessary, during the closing operation proper, and helps to stiffen them in the direction of their height, while the second bending contributes to the facilit of the same execution which would be 0t erwise interfered with by the second ring. I

It is generally advantageous to design the tongues 0 so that they should adjoin three ribs, as shown in Figs. 8 and 9, and it is better in any case to extend the ribs, limit ing them, along a certain length of the tongues as shown, for instance, in Fig. 10.

It is obvious that the invention is by no means limited to the constructions described. It comprises, on the contrary, any modifications such as those, for instance, in which smaller resistance, or even no resistance at all, is given to the portions of the capsule comprised between thetongues, which latter are thus caused to play the'greater part or even the whole function of the system.

In any gase it must be understood that the system to which Figs. 810 relate, is by no means limited to the use with the double ring; the said sysi. m, can on the contrary, be used with advantage in the case of a single ring.

What I claim as my invention and desire to secure by Letters Patent is The combination with a bottle having a head provided with an annular locking shoulder, of a capsule corrugated into locking contact with said shoulder and provided with extended rentering'portions in relation to a part of the corrugations to increase the extent of the capsule in the direction of its height, the capsule also being pro- 1 vidcd with depending tongues extending from a art of the corrugations and in alinel ment with a part of the reentering portions between the corrugations fxmn Whivh the 11211118 to this specification in the presence of tongues ezdztend, whireby when thi tc ngues two subscribing witnesses. are. move u ward y by manual Iux-ce the 5 w ,7 1 \m 1 portions of tl ze' Capsule fhereabove are bent fix L K 5 on a line passing approximately through the \Vitnesses:
